Yhm Black Diamond M-lok - Forearm Ar-15 Mid-length

The Yhm Black Diamond M-lok Forearm AR-15 Mid-length handguard from Yankee Hill Machine is purpose-built for shooters and operators who demand a lightweight, modular rail platform without sacrificing structural integrity. Designed for mid-length gas systems, this forearm delivers the balance between ergonomics and accessibility that professionals require in tactical, competition, and duty rifle configurations. Whether you're running a patrol carbine, precision intermediate rifle, or specialized platform, the Black Diamond's minimal footprint and robust construction make it an ideal upgrade for shooters seeking rail real estate without excess weight penalty.

Constructed with precision machining and hard-anodized aluminum, the Yhm Black Diamond features full M-lok compatibility, allowing you to attach industry-standard tactical accessories—vertical grips, light mounts, sling attachment points, and forward-mounted optics—at any position along the rail. The mid-length configuration optimizes sight radius for AR-15 platforms while maintaining a compact profile that reduces sight obstruction and supports natural shooting geometry. At 0.85 lbs, the lightweight design minimizes muzzle rise and fatigue during extended shooting sessions, critical for law enforcement duty rotations and tactical training scenarios where every ounce impacts target reacquisition and shooter endurance.

This handguard is engineered for mid-length gas tube AR-15 upper receivers, making it compatible with standard mil-spec platforms and modern piston systems alike. Installation follows conventional handguard swap procedures—remove the delta ring and snap ring, slide the Black Diamond into position, and secure with the barrel nut. Law enforcement armorer teams and end-users appreciate Yankee Hill Machine's reputation for no-frills, combat-proven components that prioritize reliability over marketing aesthetics. The Black Diamond's proven track record in active service and competitive environments makes it a trusted choice for operators building or upgrading rifles that must perform under demanding conditions.
